Access encoder configuration menu

Navigate to MOD function → Encoder Configuration → Select affected axis encoder

Document current encoder settings before making changes

Verify encoder type and parameters

Check encoder model number matches machine parameter MP6510 (encoder type) and MP6520 (lines per revolution)

Incorrect encoder parameters can cause axis positioning errors

Reset encoder configuration

Execute 'Accept new encoder configuration' in encoder setup menu to recalculate and store new checksum

Perform reference point approach

Execute reference point run for affected axis to establish new encoder zero position

Check encoder cable connections

Inspect encoder cable connections at motor and TNC encoder input modules for loose or corroded contacts

Power down system before checking connections

Verify encoder signal quality

Use TNC diagnostic screen MOD → Diagnosis → Encoder signals to check signal amplitude and quality

Look for signal levels between 0.6-1.4V for proper operation

Clear alarm and reinitialize

Clear alarm with CE key, then navigate to encoder configuration and select 'Restore encoder settings'

Test axis movement

Perform manual axis movement in incremental mode to verify encoder feedback is functioning correctly

Access machine parameter overview

Navigate to MOD → Machine Parameters → MP651x series to review encoder-specific parameters

Compare with machine documentation or backup parameter file

Verify encoder type parameters

Check MP6510 (encoder type), MP6520 (encoder resolution), MP6530 (encoder monitoring) match physical encoder specifications

Restore correct parameters

Input correct encoder parameters based on encoder nameplate data or machine documentation

Save parameters and restart

Save machine parameters with END key and perform control restart to reinitialize encoder configuration

Check backup battery status

Navigate to MOD → System Info → Battery status to verify backup battery voltage is above 3.0V

Replace battery immediately if voltage is below 2.8V

Restore from parameter backup

Load machine parameters from backup file using MOD → File Management → Load machine parameters

Reconfigure encoder settings

Navigate to encoder configuration menu and re-establish encoder parameters for all axes

Create new parameter backup

Save current working parameters to backup file for future recovery

Test encoder communication

Use TNC encoder test function in MOD → Diagnosis → Encoder test to verify encoder responds to queries

Check encoder error status

Review encoder-specific error bits in diagnostic display for internal encoder faults

Attempt encoder reset

Power cycle the encoder through TNC encoder power control or system restart

Replace encoder if necessary

If encoder fails communication tests, replacement is required with subsequent configuration setup

Encoder replacement requires precise mechanical alignment and calibration
